Abstract
The metabolic component of refractivity is considered as an example of a quantifying parameter for the 'vitality' of cells and organelles. It is shown that intracellular processes can be studied by the dynamic phase microscopy method, whichprovides real-time information in the form of local changes in the optical path difference. Preliminary results demonstrate the possibility of localizing a 'signal' and obtaining information under the signal – structure – function scheme and show prospects for conducting a 'dialogue' with a cell by real-time registering the way in which it responds to changes in external conditions. The mechanism underlying the dependence of refractivity on metabolic states is explained by the contributionof bound water molecules.
